[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for slidably mounting a wall panel on a building frame.

[0002]

2. Description of the Related Art For example, when a wall panel formed by applying a shallow box-shaped metal panel on the surface side of an ALC plate (lightweight cellular concrete plate) is attached to a building frame, a rectangular plate-like steel plate connecting plate is attached to the wall. One or two panels are arranged at each end in the longitudinal direction of the panel, and one end of this connecting plate is bolted to the back surface of the ALC plate, and the other end is welded to an angle member fixed to the building frame. Generally adopted. An elongated hole extending in the longitudinal direction of the wall panel is formed in the connecting plate, and a bolt for fastening the connecting plate penetrates the elongated hole.
The relative movement between the C plates can be absorbed.

[0003]

By the way, when the interlayer displacement occurs, between the connecting plate and the wall panel, not only a linear movement in the longitudinal direction of the panel but also a bolt for tightening due to the rocking movement is performed. However, since the conventional bolt does not have a secure locking means as long as a spring washer is used, there is a high possibility that the bolt will be loosened, and safety is not improved. It was not a good thing.

[0004] This invention solves the above-mentioned conventional problems, in which the wall panel can be slid in the longitudinal direction with respect to the connecting plate for mounting the wall panel, and a connecting plate fastening bolt or bolt is used. An object of the present invention is to provide a structure of a mounting portion of a wall panel that can reliably prevent a nut from loosening.

[0005]

SUMMARY OF THE INVENTION Therefore, the first of the present application is described.
The structure of the mounting part of the wall panel according to the invention of the present invention is characterized in that the fastening plate part connected to the fixing plate part has an elongated hole extending in the longitudinal direction of the wall panel. A seat plate provided with a detent piece and a bolt hole facing each other with a clearance on the side surface of the attached plate portion is overlapped, and the bolt is passed through the bolt hole and the elongated hole and screwed into the wall panel, and tightened to the back surface of the wall panel, The head of the bolt is welded to the seat plate, and the fixing plate portion of the connecting plate is welded to a support member fixed to a building frame.

The structure of the mounting portion of the wall panel according to the second invention of the present application is such that a fastening plate portion connected to a fixing plate portion is provided below a seat plate having a bolt hole in a longitudinal direction of the wall panel. The fastening plate portion of the connecting plate, which is provided with an elongated hole extending and a detent piece opposing the side surface of the seat plate with a clearance, is overlapped, and the bolt is passed through the bolt hole and the elongated hole and screwed into a wall panel. Tighten to the back of the wall panel ,
The head is welded to the seat plate, and the fixing plate portion of the connecting plate is welded to a support member fixed to the building frame.

[0007]

In the structure of the mounting portion of the wall panel of the present invention, when an interlayer displacement occurs in the building frame due to an earthquake or the like, the connecting plate slides along the back surface of the wall panel, and the bolts of the fastening plate portion. Since it moves in the elongated hole, an excessive load is not applied to the bolt and the connecting plate.

[0008] Even when the wall panel and the connecting plate are relatively rotated around the bolt , excessive rotation of the seat plate in the direction in which the bolt is loosened is caused by the contact between the detent piece and the side surface of the fastening plate. (In the case of the first invention ) or by abutment of the detent piece with the side surface of the seat plate (in the case of the second invention ), the bolt integrated with the seat plate is fixed to the detent piece at the time of installation. It does not loosen more than the angle corresponding to the set clearance between the fastening plate and the side surface of the seat plate.
